Here is a selection of calibration related articles that we have put together over the years.
Some are on general aspects of calibration and others are an in-depth analysis of some Calibration Toolbox ADO's specialist features.
Hope you will find them useful and entertaining.
ISO/IEC/EN 17025 - General Requirements for the Competence of Calibration and Testing Laboratories.
This article discusses the requirements needed to follow ISO 17025 and the benefits to be gained
Good Laboratory Practice
Principles of GLP and Compliance Monitoring - Good Laboratory Practice
Among the topics discussed are:
* Who Needs to Comply?
* Who Governs and Monitors GLP?
* What is the Purpose of Calibration Management Within GLP?
* Validated Calibration Management Systems
Software Validation Guide.
This article discusses software validation and the Calibration Toolbox ADO Software Validation Pack.
* Software Validation and Verification
* The U.S. Food and Drug Administration (FDA) definition of software validation
* The Calibration Toolbox ADO Software Validation Pack
This article discusses the requirements needed to calibrate laboratory balance to international standards such as:
- UKAS LAB 14
- NIST Handbook 44
- MSL New Zealand: Technical Guide 25
We also demonstrate how Calibration Toolbox ADO - using its balance interface can save a great deal of time whist reducing data transfer and calculation errors.
An Introduction to Regression Analysis
This article introduces the principles of regression analysis and how it can be used in the calibration process.
* Regression Coefficients
* Correlation
* Interpolation
The article also discusses how regression analysis is used in Calibration Toolbox ADO.
Pipette Calibration.
Calibration of pipettes using the gravimetric method is a specialist calibration type fully supported in Calibration Toolbox ADO.
This article, which assumes a basic knowledge of pipette calibration, illustrates how productivity and accuracy can be greatly improved by using the semi-automation approach that Calibration Toolbox ADO provides.
* Balance Interface
* Inaccuracy and Imprecision
* Production of Calibration Certificates
The article also discusses how to produce test plans (known in Calibration Toolbox ADO as "Calibration Data Templates") for each type of single and multi-channel pipette.
Type-A Measurement Uncertainties.
The calculation and use of measurement uncertainties is well supported in Calibration Toolbox ADO.
This article introduces the principles of Type-A measurement uncertainties, coverage factors and other properties associated with the derivation of measurement uncertainty. It also shows how they can be calculated quickly and easily using Calibration Toombox ADO.
Type-B Measurement Uncertainties.
This article introduces the principle of Type-A measurement uncertainties
The article also discusses how to measurement uncertainties are expressed in calibration certificates abd other documents.
